Application filed November 21, 1930. Serial No. 437,310.

an improved machine for winding motor coils, wherein provision will be made for adjustment to enable coils of different sizes and she es to be wound on the same machine, merely y adjusting the machine according to the size and shape that it is desired to prom toned to a table or bench. Journaled d'uce.

Preferably, an indicator or counter is used to automatically show the number of windings in the coil, thus enabling the operator to wind a coil of any desired number of turns.

The invention comprises an improved rotary reel which may be turned by motor or hand crank, having fingers which are adjustably mounted so that they may assume different positions, together with improved means for locking the fingers where adjusted, improved adjustable hooks for the fingers, and other improved features and novel combinations hereinafter described and which are shown in the accompanying drawings, wherein:

Figure 1, is a front elevation, dot and dash lines representing one of the adjusted positions of the fingers and the outline of a different size and shape of coil which may be produced by such adjustment;

Fig. 2, is a side elevation with certain parts broken away;

Fig. 3, is a detail view of one of the hooks, certain parts being broken away;

Fig. 4, is a. detail view of the disc, and a pair of fingers and links therefor, shown detached from the machine; and

Fig. 5, is a detail view of the rotatable huh by itself, showing the plurality of holes therein.

The operative parts of the machine are carried by a frame 1 whose base may be has bearing 2 on the frame 1 is a shaft 3, which projects beyond one face of the bearing to carry the operative parts hereinafter scribed. A crank t is carried by the other end of the shaft. In-lieu of the crank. 4., any gearing or belt and pulley drive gear may e used, driven by an electric motor.

Secured to the shaft 3 so as to turn therewith is a hub 5 which carries rods 6 constituting spokes for a reel whose. band 7 is suitably connected to the spokes 6.

The reel comprising the spokes 6 and the band 7, constitutes the carrier for the coil winding structure. To afi'ord means showing the number of revolutions of the shaft 8, there may be provided an indicator 8 having a pinion 9 which meshes with a gear 19 carried by the hub 5. This indicator 8 shows shaped disc 11 which is provided with an op ming 12 through which a removable pin 13 may be passed and entered into any one of a plurality of holes 14 in the hub 5, as shown in Fig. 2, thereby to couple the disc 11 to the hub 5. As many of the holes 14 may be provided as necessary, to afford adjustments which are hereinafter described.

There are two sets of fingers, all of which are used in winding the coil 15, which appears in full lines in Fig. l and also in dot and dash lines at 16 in said figure. One set of these fingers comprises the individually adjustable fingers 17 which are pivoted at their inner ends within the groove of the disc 11 by the pivots 18, Fig. 1.

The other set of fingers 19, instead of being directly pivoted to the disc 11,-are pivotally connected at 20 to a link 21 in each instance. The link 21, in each instance, is pivotally connected at 22 to the disc 11. The pivotal connections 20 are of the type which can be clamped as, for instance, a bolt and not or bolt and wing nut, as in Fig. 2, so that the fingers 19 will be rigid with the links 21 justed and re-clamped loosening the joint 20, a collapsing action will occur, under the tension 0 the wound coil 15 to enable the coil to be removed, as hereinafter described.

Each of the fingers 17, 19, is rovided with a sleeve 23 which is swivelle at 24 to an adjustable connector 25 having a slot which receives the edge of the band or rim 7 and is adapted to be secured thereto by a set screw 26 in any position to which the finger may be adjusted. 7

All of the fingers carry adjustable hooks of the construction appearing'in Fig. 3. These hooks comprise a connector 27 havin a hole 28 through which passes the finger 1% or 19, as the case may be enabling the hook to be adjusted radially along the finger to any desired point, and there is a set screw 29 -by which the connector may be secured where adjusted. The hook 30 itself has its shank received in a socket 31 in the connector 27 and secured therein by a set screw 32. It will be observed that the hook and the face of the connector each has a flat surface 33 which surfaces collectively constitute walls, determining the width of the coil 15. By adjusting the hook inwardly or outwardly, this width may be varied.

Assuming that the parts are set, as shown in full lines in Fig. 1, the connections being clamped right, the coil represented at 15 may be wound in the hexagonal shape shown. If a coil of different shape is desired, the connectors 27 and their hooks are slid along the fingers and the fingers themselves adto the band 7 so that a coil such as shown at 16 in dot and dash outline, may be wound. Thus, an desired size and shape of coil may be woun by turning the crank 4.

If it is desired to remove the coil which has been wound, the connectors 20 are loosened and the pin 13 is pulled out of the hole 14, whereupon, if the reel is turned about one fourth of a revolution, the fingers 19 will draw in toward the shaft 3, allowing the hooks on the fingers to travel closer to thel center of rotation, thus releasing the CO1 What I claim is: Y

1. In a machine for winding coils for electric motors, the combination witha rotary wheel, of fingers carried thereby having means adjustable along said fingers,

for supporting the coil which is to be said fingers being adj ustably connected to the band or rim of the wheel and pivotally conadapted nected to the central part of the wheel.

2. In a machine for winding coils for electric motors, the combination with a rotary wheel, of fingers carried thereby having means adjustable along said fingers, adapted for supporting the coil which is to be wound, certain ones of said fingers having a pivotal connection to the central part of the wheel wound,

tric motors, the combination with a wheel having a rim and a hub, of a disc, means for coupling the disc to the hub and by which said disc may be uncoupled from the hub so that it will turn inde endently of said hub, fingers pivoted to t e hub and having adjustable connections with the rim, other fingers connected to the hub by links and provided with means by which the links may be rigid with said fingers or loosely connected to said fingers means adjustably connecting the said other fingers to the rim, and coil supports carried by all of the fingers, said supports being adjustable along the said fingers.

4. In a machine for winding coils for electric motors, the combination with a wheel, of a plurality of fingers, means adjustably mounted on said fingers and adapted for supmay be pivotally connected to the links or made rigid with said links. In testimony whereof I aflix my si ature.
